Every May 5, it is Kodomo no Hi or "Children’s Day" in Japan. Families fly koinobori banners in the shape of a carp (a type of fish) for each child in their house. In Japanese folklore, the carp is a symbol of determination and vigor, overcoming all obstacles to swim upstream. Samurai warrior figurines and samurai kabuto helmets are also displayed in homes to inspire strength and bravery. Japanese Classes made kabuto heimets and wore them.
